Abstract

This study was conducted to examine variations of 35 morphological characteristics of 6 natural populations of Zelkova serrata in Korea. On the basis of the results of the ANOVA tests, the populations were significantly different in 16 of the 20 quantitative morphological characteristics that were tested. In particular, the 'Cheongju-si Gutdae Mountain' population showed larger values in 9 of the 20 quantitative characteristics that were examined. In the results of principal component analysis of the characteristics, examined characteristics were not suitable for the variation of 6 natural populations. According to the results of cluster analysis, 'Namhae-gun Mijori Evergreen Forest' population was grouped with 'Yangpyeon-gun Yongmun Mountain' population to the nearest group, and then 'Cheongju-si Gutdae Mountain' population, 'Boeun-gun Sokri Mountain' population, 'Daegu metropolitan city Palgong Mountain' population, and 'Hamyang-gun Sang Forest' population were grouped in regular sequence.

국내에 분포하는 느티나무의 표현형의 변이를 확인하기 위하여 자생지 6곳을 대상으로 35가지 형태적 특징을 조사하였다. 분산분석 수행결과 20가지 정량적형질 중 16가지 형질이 집단간에 유의한 차이를 나타내는 것으로 확인되었다. 특히, '청주시 것대산' 집단이 20가지 정량적형질 중 9가지에서 최대값을 나타내었다. 주성분 분석 결과 측정항목들이 집단 간 차이를 나타내는데 적절하지 못함이 확인되었다. 군집분석을 수행한 결과 '남해군 미조리상록수림' 집단과 '양평군 용문산' 집단이 가장 가까운 그룹을 이루었으며, '청주시 것대산' 집단, '보은군 속리산' 집단, '대구광역시 팔공산' 집단, '함양군 상림' 집단 순으로 군집되었다.
